An example of knowledge visualization on the move 🙂 from Oxford, UK.
The period table is probably the most amazing example of knowledge visualization: it enables insights (indeed, to understand that some elements were not yet discovered!), offers overview-zoom, and details on demand (if you have an interactive version) as in Schneiderman’s mantra, it’s color coded for an easier navigation, and can also be used for visually pleasant marketing activities, as above!

Professor Holenstein just gave an interesting seminar at USI on the cultural differences in the representation of space. He is one of the world major expert on the topic. He is the author of the Atlas of Philosophy (2004).
I found interesting to hear his philosophical perspective on a topic I am particularly interested in, which is typically addressed from a mere cognitive point of view. He showed how Japanese people depict their country, with the main axes east-west. while we typically think of Japan as a land that is mainly distributed vertically (north-south) like Italy.
He also reflected on how geographical maps cannot be objective depictions of reality but a product of what the cartographer wants to emphasize. Therefore I suppose they can as well be considered knowledge visualization, with a close mapping to the original distribution of information.
The traditional world map is a product of conventions, indeed many types of world maps exists with different orientations, upside down or east-west, like this Japanese map of 1671:

I have posted earlier on the increasing use of visualization from the social media community. Now it is not only about information visualization; there are also beautiful infographics and useful knowledge maps. See this collection of Web 2.0 knowledge maps for an overview: From mindmaps and matrices, to visual metaphors and process diagrams. (Thanks Alex for the pointer!)
